EN26 Alloy Steel Round Bars

EN26 Alloy steel Round Bars is often used in demanding applications such as gears, shafts, and axles in the aerospace, automotive, and industrial sectors.

 Details Regarding EN26 Alloy Steel Round Bars:

Chemical Composition (approximate values):

Mechanical Properties:

• Tensile Strength: 850-1050 MPa
• Yield Strength: 650-800 MPa
• Elongation: 15-20% (in 50 mm)
• Hardness: 280-330 HB

Physical Properties:

• Density: ~7.85 g/cm³
• Melting Point: ~1420-1470°C

Heat Treatment:

EN26 alloy steel typically undergoes various heat treatment processes to achieve desired mechanical properties:

Annealing: Heating the material to around 850-900°C and then slowly cooling it in the furnace to relieve internal stresses and improve machinability.

Normalizing: Heating the material to around 880-920°C, followed by air cooling to room temperature. This process refines the grain structure and enhances the mechanical properties.

Hardening: Heating the material to a temperature range of 850-900°C and then quenching it in oil or water to achieve high hardness and strength.

Tempering: Reheating the hardened material to a temperature range of 550-650°C and holding it for a specific time to reduce internal stresses and improve toughness without significantly sacrificing hardness.
